Help Help please sa globe at home prepaid!!!

[Munch1968]

Bumili ako ng new globe at home sim kasi expired na yung kasama ng globe at home Dahil matagal na Di nagamit. Then need to change the imei. I followed an instruction from YøùTùbé kaso after changing the imei nag instruct sya to openline for pldt sim. Ayun ngayon pag nagla-log in ako nakalabas SI'M LOCK contact your system administrator. .. Wala na signal. Help pano po ayusin to. Salamat
